If you want to use movie clips in your ministry, the first thing you need is a great resource (or more than one) which helps you find the perfect clip for your subject.  The best (and easiest) I've found are three books by an author named Bryan Belknap.  His books are called Group's Blockbuster Movie Illustrations Volume I,II and III.  They are nicely indexed and are filled with great clips which focus on a wide variety of themes, have scriptural tie-ins and included several discussion questions.  And best of all, they are definitely not filled with lame and unusable suggestions which you would never use with your teens.  I highly recommend these books.  You can check out my full review on the Free Programming page at the By The Way Ministries web site which includes a link to where you can buy the books.
